Abstract:Sinusoidal phase-shifting symmetrically combined with cyclic code is
one of the most important encoding methods in the field of 3D
measurement. Due to the modulation of the object surface and the
influence of the noise of the image acquisition system, the periods of
the cyclic code and the sinusoidal phase-shifting in the intensity
image do not coincide completely, and they lead to large absolute
phase decoding errors near the cycle boundaries, which are called
cycle dislocat… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
